91 Oldsmobile Cutlass Ciera S 3.3L V6 3 speed w/OD 129,367K miles as of today...
From 89K miles. Had to drop pan everytime..
89K miles FEB11, Drain and fill, + filter and gasket. 6 qts Maxlife + lubred.
98K miles, APRIL11 D&F +F&G 6 qts Maxlife. + lubred
98K miles APRIL11(YES twice! had to drop the pan 6 miles later to FIX a lose filter.. It would drop out of gear, and SLIP like mad inbetween shifts.) Had to drain out lubred and new maxlife.. i was upset lol.. replaced with 3QTs castrol DEX, 3 qts castrol HM..
112K miles JULY11 Drain and fill, + filter and gasket.. 6 QTS castrol forgot to put magnet back in pan.....
122K miles, SEPT11 Drain and fill + filter and gasket, again 6 qts castrol.. Still forgot to put in magnet..
129K miles, NOV11 Drain and fill + filter and gasket. 6 qts maxlife, and it has NEVER shifted better.. The change was night and day from the castrol.. Even though i change the fluid about every 3 months, this last change has the MOST noticeable improvement.. It shifts so smooth, the gears slide in to the next without much clutch slippage, but yet, its not giving you whip lash.. oh, and yes, lost that magnet... ill pick up a new one, and hopefully not forget to install it.. LOL.
Cant agree more. Maxlife seems to be a very good fluid, and with the Advanced codes, you can pick it up for CHEAPER then going to walmart for 5$/QT castrol
Its changed so often because its driven in lost NY, country roads, mountains, engine braking, WOT to triple digits, shifting often from 1-3, even in and out of OD.. Its the last thing the tranny needs is extended drains...

Would HIGHLY recommend this fluid for older trannies that spec Dexron. Shifts very smooth & quiet. And fluid was inexpensive at my local AutoZone.
